Hoxb1 Gene Summary [Mouse]
Enables sequence-specific DNA binding activity. Contributes to RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including central nervous system development; embryonic skeletal system morphogenesis; and positive regulation of transcription by RNA polymerase II. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including branchial arch; central nervous system; embryo ectoderm; embryo mesenchyme; and gut. Orthologous to human HOXB1 (homeobox B1).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Hoxb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
